An outlet valve for a dispensing nozzle comprising a first valve component constructed and arranged to be received by the dispensing nozzle and a second valve component constructed and arranged to cooperate with the first valve component. The first valve component and the second valve component define a normally-closed flow interface.

A cartridge for selectively dispensing an additive to water that includes a housing, a bladder disposed within the housing, and a pump connected to the housing and in fluid communication with the bladder. The bladder is configured to contain a consumable additive such as a flavor, for water. The pump is operable to selectively dispense an amount of the additive into water. The cartridge may be connected to a water filtration system such that the cartridge may dispense the additive into filtered water.

A liquid soap dispenser includes a container having a flexible outer wall and including a quantity of liquid soap therein. The upper surface of the container can be moved between an upper position and a lower position but is spring biased into the upper position. A pump within said container pumps a portion of the liquid soap onto the upper surface when it is moved downwardly into its lower position. A normally closed valve at the bottom of the container opens to dispense liquid soap from the bottom of the container when the container is squeezed.

Some embodiments are directed to a valve, including a rigid end piece that defines a center; a rod at the center of the end piece defining an axis; and a flap, wherein the flap is in one piece and has a flexible wall situated opposite a free end of the rod, the flexible wall is perforated by an orifice concentric with the end of the rod, the orifice has a contour substantially homothetic with that of the contour of the end of the rod in a plane perpendicular to the axis of the rod, the orifice has a surface below a projected surface of the end of the rod in the plane, the flap is connected to the end piece by a non-deformable fixed connection, and the flexible wall presses against the end of the rod at any point of its surface in contact with the end.

The invention relates to a method for dispensing viscous or pasty ingredients (12), which are packaged in an aseptic manner, from a tubular bag (1), which is closed prior to the first use, by means of a disposable pump (4) attached to the bag. The disposable pump (4) has an inlet (5) with a cutting element (6), and a nozzle (2) with a flange (3) is welded onto the tubular bag (1). The disposable pump (4) is rotated relative to the nozzle (2), and the tubular bag (1) is thereby cut open. A valve (9) is arranged in the region of the outlet opening of an outlet tube (8) of the pump, and the disposable pump (4) is operated after the initial opening process until a freely selectable volume has exited the closing valve. The disposable pump (4) is then operated in the opposite rotational direction in order to suction ingredients (12) present on or in the region of the valve (9) back into the outlet tube (8). In the process, the valve (9) reaches or remains in the closed valve state. A valve (9) is proposed for carrying out the method. The valve is arranged in the outlet tube (8) and comprises a membrane (93, 191) which is sealingly mounted in a sliding manner or can be inverted. Using the method, the ingredients (12) can be dispensed in a metered manner from a tubular bag (1), in which the ingredients are aseptically packaged, into virtually aseptic containers until the ingredients are practically completely used.

The invention relates to a dispensing device (1) having a pump device (2), which has an actuating element (5) having an output opening (12), wherein the actuating element (5) is movably arranged relative to a hearing element (6), which is connected to a pump housing (7) in a rotationally fixed manner in the usage position, wherein the actuating element (5) is rotatably arranged relative to the bearing element (6) and the bearing dement (6) has at least one protruding bridge (25) having an upper stop edge (24) and a substantially tubular portion (5) of the actuating element (5) has, on the inner surface thereof, distributed over the circumference, at least two stages (22,22, 22) defining a different displacement path, of which stages, depending on the rotational alignment of the actuating, element (5), one stage (22, 22, 22) contacts the stop edge (24) in a lower displacement position.

A system for accurately dispensing small droplets from a positive displacement pumps is actuated by a linear actuator. Preferably the linear actuator is a piezo-actuator. In a method to use the device the system pressure is stabilized before dispensing a plurality of droplets.

A container for viscous liquid is revealed. A first cover set with a one-way valve and a second cover arranged with a flow control valve are disposed on two ends of a main body of the container respectively. The first cover is suspended on a supporting member. Thereby a force is applied to the main body for pouring out viscous liquid such as caramel. Thus caramel pushes against a dome of the one-way valve and a gap on the dome is opened to make the caramel out. Once no force is applied, external air flows through a gap between the flow control valve and the second cover to push a flexible piece of the flow control valve and enter the main body. Thus both the main body and the dome of the one-way valve return back to the original shape. Thereby the caramel can be handled easily.

A dispensing closure for dispensing a flowable product from a squeeze-type product container includes a closure body having an upper deck, an exit orifice, and a skirt configured to attach to the product container. A measuring reservoir is received in engagement with a lower surface of the upper deck. The measuring reservoir is filled with a measured dose of flowable product through flow ports when the container is inverted. A piston valve is slidably movable within the measuring reservoir between an open position and a closed position. The piston valve is movable from the open position to the closed position to dispense the measured dose of product responsive to pressure within the container induced by squeezing.

A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.
